Data resource anomaly detection

ABSTRACT

Anomaly detection is provided. A first component of a first data resource of a plurality of data resources is identified. Each data resource of the plurality of data resources includes one or more components. A score of the first component is determined based, at least in part, on underlying data of the first component and underlying data of one or more other components of data resources of the plurality of data resources that correspond to the first component. An interest level of the first data resource is determined. A relationship between the score of the first component and the interest level of the first data resource is modeled.

BACKGROUND OF THE INVENTION

The present invention relates generally to the field of data mining and more specifically to analysis of resources within a data set.

A data set is a collection of data resources. A data resource may include one or more graphs, charts, diagrams, text portions, images, videos, or other organized portions of data. Each such portion of data can be described as a component within a data resource of the data set. Large quantities of data resources are often organized into one or more data sets. Big data is a term used to describe a quantity of data resources so large that that processing, analysis, or using the data resources is difficult. Big data is difficult to work with and limitations arise (e.g., for scientists and researchers) due to the amount of data. These limitations can also affect, for example, internet searching and business analytics. Data mining is often used to mitigate these limitations. Data mining uses information about data resources within a data set to understand the structure of the data set and discover patterns therein.

Current data mining systems can use data resource metadata in determining the structure and patterns of a data set. The metadata of the data resource is data about the information contained in the resource (e.g., that it is a chart about bike sales, or a graph about the weather). A data resource can include one or more distinct pieces of metadata, each of which describes one or more components of the data resource. A piece of metadata corresponds to each component that the metadata describes. Current data mining systems often rank data resources based on the data resource metadata.

DETAILED DESCRIPTION

A data resource contains one or more components, each of which corresponds to metadata that describes the characteristics and content of the component. A component is, for example, a graph, chart, or portion of text. Data mining systems catalog metadata of one or more data resources. Embodiments of the present invention recognize that current data mining systems rank and organize data resources based on the data resource metadata. Embodiments of the present invention provide for ranking or categorizing a data resource based on a data resource score, which is an aggregation of one or more component sub-scores of the data resource. Each component score reflects the importance of a component to a user. Thus, the data resource score represents the importance of the data resource to a user. The subset of data resource metadata is the basis for the data resource rank and is likely more relevant to a user. Embodiments of the present invention provide for highlighting, exposing, or otherwise indicating one or more components of a data resource.

The present invention will now be described in detail with reference to the Figures. FIG. 1 is a functional block diagram illustrating a computing environment, generally designated 100, in accordance with one embodiment of the present invention. Computing environment 100 includes client device 120 and server computer 130 interconnected over network 110. Network 110 may be a local area network (LAN), a wide area network (WAN) such as the Internet, any combination thereof, or any combination of connections and protocols that will support communications between client device 120 and server computer 130 in accordance with embodiments of the present invention. Network 110 may include connections such as wired, wireless, communication links, or fiber optic cables. Computing environment 100 may include additional servers, clients, and other devices not illustrated.

Server computer 130 may be a management server, a web server, or any other electronic device or computing system capable of processing program instructions and receiving and sending data. In some embodiments, server computer 130 may be a laptop computer, tablet computer, personal computer (PC), desktop computer, or any programmable electronic device capable of communicating with client device 120 via network 110. In other embodiments, server computer 130 represents a computing system utilizing multiple computers as a server system, such as in a cloud computing environment. In another embodiment, server computer 130 represents a computing system utilizing clustered computer and components to act as a single pool of seamless resources. Server computer 130 includes data set 134, which includes one or more data resources (e.g., data resource 136 a, data resource 136 b), collectively referred to as data resources 136. Each of data resources 136 includes one or more components (e.g., component 138 a and component 138 b), collectively referred to as components 138. In other embodiments, server computer 130 may include internal and external hardware components, as depicted and described in further detail with respect to FIG. 5.

Data set 134 may be any collection, storage, or repository of data resources like data resources 136. In some embodiments, data set 134 collects and stores data resources like data resources 136. As illustrated in FIG. 1, data set 134 may be located within server computer 130. In other embodiments, data set 134 may be located on another computing device (e.g., client device 120) or may be a separate device, as long as data set 134 is accessible by server computer 130. In some embodiments, data set 134 may be written to and read by programs and entities outside of computing environment 100, for example, in order to populate the repository with data resources 136. FIG. 1 is intended merely as one example and not as an architectural limitation for the present invention.

Each of data resources 136 is an organized body of data that includes one or more components 138. In one embodiment, each of data resources 136 is a report generated by a big data analytics system. In other embodiments, each of data resources 136 may be a web page, image, video, or other organized portion of data or content accessible (e.g., via network 110) to computing devices (e.g., server computer 130, client device 120). Each component 138 may be a graph, chart, diagram, text block, image, video, or other organized portion of data. Each of data resources 136 may have multiple components 138. Data set 134 may include large quantities of data resources 136, each having one or more components 138. Data set 134 may represent a plurality of data sets, each having one or more data resources 136 that each, in turn, have one or more components 138.

An example of data resources having multiple components is depicted in FIG. 4, in which data resource 410 has components 411, 412, 413, and 414, and data resource 420 has components 421, 422, 423, and 424. The components of data resource 410 and data resource 420 correspond to one another. In one embodiment, components are arranged within data resources in a certain order. In this case, each component of a data resource corresponds to the components of other data resources at the same sequential position. For example, each data resource includes an array of components, in which case components of different data resources at the same array index correspond to one another. In the depicted example, components 411, 412, 413, and 414 correspond to components 421, 422, 423, and 424, respectively. In one embodiment, components that correspond to one another pertain to the same subject matter but represent different underlying data. For example, component 413 and component 423 may each include a chart of quarterly sales figures for a given line of products, where each chart reflects data from a different quarter. In another example, component 412 and component 422 may each include a portion of text such as a survey response, in which case the text of the survey response may differ from component 412 to component 422. In another embodiment, a plurality of corresponding components may depict the same underlying data. In one embodiment, corresponding components have the same metadata. In another embodiment, anomaly detection program 132 maps the components of a data resource to index positions based on the metadata of the data resources, such that each component is in the same index position as the components to which it corresponds.

Client device 120 may be, for example, a personal computer, desktop computer, laptop computer, netbook computer, tablet computer, personal digital assistant (PDA), smart phone, or other computation and/or communication device. In general, client device 120 may be an electronic device or computing system capable of processing program instructions and sending and receiving data and communicating with server computer 130 may be any electronic device or computing system capable of processing program instructions and sending and receiving data and communicating with server computer 130 over network 110. Client device 120 may include internal and external hardware components, as depicted and described in further detail with respect to FIG. 5.

Client device 120 includes a user interface (UI), client UI 122, which executes locally on client device 120 and operates to provide a UI to a user of client device 120. Client UI 122 further operates to receive user input from a user via the provided user interface, thereby enabling the user to interact with client device 120. In one embodiment, client UI 122 provides a user interface that enables a user of client device 120 to interact (e.g., via network 110) with anomaly detection program 132 of server computer 130. In one example, client UI 122 presents the user of client device 120 with indicators generated by anomaly detection program 132 to indicate anomalies to the user. In one embodiment, client UI 122 is stored on client device 120. In other embodiments, client UI 122 is stored on another computing device (e.g., server computer 130), provided that client UI 122 can access and is accessible by at least anomaly detection program 132.

Anomaly detection program 132 is stored on server computer 130. In one embodiment, anomaly detection program 132 operates to identify anomalies among data resources (e.g., data resources 136). In another embodiment, anomaly detection program 132 operates to generate indicators for data resources 136, components 138, or both. In various examples, anomaly detection program 132 identifies anomalies in data resources 136, components 138, or both based, at least in part, on anomaly scores of components 138 and, in response, anomaly detection program 132 generates indicators for the data resources 136, components 138, or both for which anomalies were identified. In one embodiment, an indicator adjusts an ordering of presentation of one or more components 138 of a data resource of data resources 136. Alternatively, an indicator identifies, exposes, formats, or otherwise indicates the anomalous data resources 136 and/or components 138 based upon which anomaly detection program 132 detected an anomaly. For example, an indicator may modify the manner in which a data resource (e.g., data resource 136 a) is presented to a user (e.g., via client UI 122).

FIG. 2 is a flowchart depicting operations for anomaly detection, on a computing device within the computing environment of FIG. 1, in accordance with an embodiment of the present disclosure. For example, FIG. 2 is a flowchart depicting operations 200 of anomaly detection program 132, on server computer 130 within computing environment 100.

In step 202, anomaly detection program 132 determines an anomaly score for each component of a data resource. The anomaly score for a component represents the degree to which the underlying data of the component is unusual or anomalous relative to the components corresponding thereto. In one embodiment, anomaly detection program 132 determines an anomaly score for a component by comparing the component to one or more corresponding components. For example, anomaly detection program 132 compares component 422 to one or more corresponding components, including component 432. In one embodiment, anomaly detection program 132 determines an anomaly score for all components of all data resources by comparing each component to all components corresponding thereto. In this case, each data resource has an anomaly score for each component of the data resource.

In some embodiments, anomaly detection program 132 may determine an anomaly score utilizing a novelty detection technique such as a multivariate Gaussian distribution, k-Nearest Neighbors algorithm, local outlier factor algorithm, cluster analysis, or any combination thereof. Further, such techniques may include unsupervised, semi-supervised, supervised anomaly detection techniques, or any combination thereof.

In step 204, anomaly detection program 132 determines an interest level for a data resource. The interest level for a data resource represents an amount of interest expressed in the data resource. For example, the interest may be expressed explicitly through user interaction or implicitly through user behavior, wherein the user is, for example, a user of server computer 130, a user of client device 120 (e.g., via client UI 122), a user of another computing device, or any combination thereof. In one embodiment, anomaly detection program 132 determines an interest level for a data resource by categorizing the data resource into one of at least two categories. The categories may correspond to uninteresting versus interesting data resources, or to data resources that are of low, medium, or high interest, or to any other categorization of a relative level of interest.

In one embodiment, anomaly detection program 132 determines the interest level of a data resource based on a received interest level for the data resource. For example, anomaly detection program 132 may retrieve the interest level from a database or, alternatively, anomaly detection program 132 may receive the interest level as user input (e.g., via client UI 122). In another embodiment, anomaly detection program 132 determines the interest level for a data resource based on user behavior in connection with the data resource. In this case, the user behavior may include a measure of the amount (e.g., duration, frequency, cumulative count) the user accesses a given data resource or particular components thereof. For example, anomaly detection program 132 determines a high level of interest for a data resource that a user frequently accesses or that a user accesses (e.g., views) for a long period of time. In one embodiment, anomaly detection program 132 determines an interest level for a data resource utilizing logistic regression to categorize the data resource based on the user behavior in connection with the data resource.

In some embodiments, the interest level is a relative measure, in which case anomaly detection program 132 compares the user behavior in connection with each data resource to that in connection with other data resources. In other embodiments, the interest level is an absolute measure, in which case anomaly detection program 132 compares the user behavior in connection with the data resource to one or more predetermined thresholds. In yet another embodiment, the interest level is a combination of a relative measure and an absolute measure.

In step 206, anomaly detection program 132 models a relationship between the anomaly score of each component of a data resource and the interest level of the data resource. The modeled relationship represents a degree of influence of the anomaly score of each component of a data resource on the level of interest of the data resource. In one embodiment, anomaly detection program 132 models the relationship by determining a weight for each component such that the weight-adjusted anomaly score of each component of each data resource predicts the interest level of the data resource when utilizing a discrete classification statistical technique (e.g., logistic regression or naïve Bayes classification). For example, anomaly detection program 132 utilizes a naïve Bayes classification to train feature weights, where the feature is the anomaly score of each component.

FIG. 3 is a flowchart depicting operations for anomaly detection, on a computing device within the computing environment of FIG. 1, in accordance with an embodiment of the present disclosure. For example, FIG. 3 is a flowchart depicting operations 300 of anomaly detection program 132, on server computer 130 within computing environment 100.

In step 302, anomaly detection program 132 identifies a data resource. In various embodiments, anomaly detection program 132 identifies the data resource by retrieving, receiving, or otherwise obtaining the data resource from server computer 130 (e.g., from data set 134), from client device 120 (e.g., from client UI 122), or from another computing device. The data resource includes components corresponding to the components for which anomaly detection program 132 modeled a relationship (see FIG. 2 and accompanying discussion). In one embodiment, the data resource includes one or more components and an anomaly score for each. In another embodiment, anomaly detection program 132 determines an anomaly score for each component of the identified data resource in a manner substantially similar to the description above in connection with step 202.

In decision 304, anomaly detection program 132 determines whether the anomaly score for a component is above a threshold. In one embodiment, the anomaly score is adjusted by a weight of the modeled relationship (see step 206) for the component. Anomaly detection program 132 performs decision 304 and, if applicable, step 306 for each component of the data resource. If anomaly detection program 132 determines that the anomaly score is above a threshold (decision 304, YES branch), then anomaly detection program 132 generates an indicator (step 306). If anomaly detection program 132 determines that the anomaly score is not above a threshold (decision 304, NO branch), then operations 300 are concluded. In one embodiment, the threshold is a value statistically determined based on the anomaly scores of all components of data resources 136 that correspond to one another. In one example, the threshold is one standard deviation above a mean of the anomaly scores. In yet another example, the threshold is a value exceeded by a certain percentage of anomaly scores. In another embodiment, anomaly detection program 132 determines that the anomaly score for a component is above the threshold if the anomaly score is the highest anomaly score of all components of the data resource. Thus, in this embodiment, anomaly detection program 132 determining whether the anomaly score for a component is above a threshold includes identifying the component of a given data report with the highest anomaly score.

In step 306, anomaly detection program 132 generates an indicator. The indicator modifies the presentation of the identified data resource. In various embodiments, anomaly detection program 132 modifies the presentation of the identified data resource by modifying the data resource, by associating the data resource with presentation modification information, or by superimposing graphics that modify the presentation of the identified data resource at the time of its presentation. In various examples, anomaly detection program 132 modifies the identified data resource with a presentation modifier (e.g., formatting instructions or markup language), associates the data resource with such a presentation modifier, or modifies the presentation of the data resource at the time of its presentation. In one embodiment, the indicator modifies a characteristic of a component (e.g., coloration, borders, shading, font, formatting, typeface, or other characteristic). Such modifications affect any part of the component (underlying data, axes, etc.). In another embodiment, the indicator modifies the presentation of the component by, for example, modifying the layout, order, or sizing of one or more components, or by adding a label to one or more components (e.g., a label that identifies the component with an anomaly score above the threshold). For example, anomaly detection program 132 may generate an indicator for a data resource by modifying the layout and ordering of the components of the data resource in order to present the component having the highest weighted anomaly score first. In this case, anomaly detection program 132 maintains the logical ordering (i.e., index position) of the components in order to preserve the correspondences between the components of the identified data resource with the other data resources 136 of data set 134.

FIG. 5 is a block diagram of components of the computing device executing operations for anomaly detection, in accordance with an embodiment of the present disclosure. For example, FIG. 5 is a block diagram of server computer 130 within computing environment 100 executing operations of anomaly detection program 134.

It should be appreciated that FIG. 5 provides only an illustration of one implementation and does not imply any limitations with regard to the environments in which different embodiments may be implemented. Many modifications to the depicted environment may be made.

Server computer 130 includes communications fabric 502, which provides communications between computer processor(s) 504, memory 506, persistent storage 508, communications unit 510, and input/output (I/O) interface(s) 512. Communications fabric 502 can be implemented with any architecture designed for passing data and/or control information between processors (such as microprocessors, communications and network processors, etc.), system memory, peripheral devices, and any other hardware components within a system.

I/O interface(s) 512 also connect to a display 520.

Display 520 provides a mechanism to display data to a user and may be, for example, a computer monitor, or a television screen.
